Allocated IP blocks
by Mike Batchelor 01 Jul '02

01 Jul '02

Is there a list anywhere of allocated IP blocks? I need to update my IDS sensor's table of valid blocks. It's alarming on some traffic coming from 67, 68 and 219, which I know were not allocated until fairly recently. Is there a simple list somewhere, i.e: 4.0.0.0/8 6.0.0.0/8 .... 219.0.0.0/24 etc... ?? --- "The avalanche has already begun. It is too late for the pebbles to vote." -- Kosh

how is cold-potato done?
by Ralph Doncaster 01 Jul '02

01 Jul '02

If I peer with network X in cities A and B, and receive the same route in both cities with an AS-path of X, how do I know which city to use for an exit? I can understand how if X uses communities to tag the geographic origin of the traffic, but I'm not aware of many networks that do this. Lots of networks claim to use cold-potato routing though, so how do they do it? Ralph Doncaster principal, IStop.com

valid IP address

Hi JothirLatha, Clearly it's possible to do this: 4500_3#conf t Enter configuration commands, one per line. End with CNTL/Z. 4500_3(config)#int lo1 4500_3(config-if)#no ip addr 4500_3(config-if)#ip addr 10.1.1.0 255.255.255.255 4500_3(config-if)#int lo2 4500_3(config-if)#ip addr 10.1.1.255 255.255.255.255 4500_3(config-if)#^Z Given that this is the group for network operators, why didn't you just try it? -David Barak "Quis custodes ipsos custodiet?" - Juvenal Date: Mon, 1 Jul 2002 07:53:32 -0700 (PDT) From: JothirLatha Jaganathan <jyothi_j(a)yahoo.com> To: nanog(a)merit.edu Subject: Valid ip address ? Can any one tell me if the last byte of a point to point or loopback ipaddress with 32 bit mask can be 0 or 255? For e.g.: Is 10.1.1.0/32 a valid interace address? __________________________________________________ Do You Yahoo!? Yahoo! - Official partner of 2002 FIFA World Cup http://fifaworldcup.yahoo.com

Here's what I've "heard" about Sprint and peering... Sprint's minimum to peer is 6 x OC-12's. To peer with them, you have to undergo a 90-day trial period. At the end of the 90 days, they will determine whether or not they would like to peer with you. Here's the catch: During the 90-day trial period, there is a NON-REFUNDABLE $125k/port fee (for each OC-12). So, you're looking at laying out $750k per month for 3 months, or $2.25 MILLION over the 90-day "trial" period, and even then, they MIGHT peer with you. But that's just what I've "heard". On a side note: Folks should keep an eye on Allegiance Internet (the folks I work for). They picked up the old Digex / Intermedia Business Internet backbone and are in the process of integrating it (under AS2548). Financially solid company, very easy to work with, and have some strong uptimes. (Plan on seeing an SLA of 99.999%/99.75%/65ms with a guaranteed 15 minute response time for loss of connectivity to customer prem and a guaranteed 40 business day install). For peering, I'm pretty sure the policy is Tier 1 = 4 points OC-3 or better, Tier 2 = 4 points DS-3 or better (Tier 2 peer pays loop charge if applicable).

Can someone provide basic details on hot potato routing (I am referring to multiple peering interconnections between 2 ISPs) ? Is it implemented by BGP or not ? Regards wg --------------------------------- Scarica il nuovo Yahoo! Messenger: con webcam, nuove faccine e tante altre novità!

Routers supporting PPPoE + IPIP tunnel
by Cho Man Fai 01 Jul '02

01 Jul '02

Because of the recent shipment problem of Cisco, I am looking seriously for a cisco 827 substitution. What I need is a router which support PPPoE + IPIP tunnel with Ethernet (or DMT) WAN port. Do you have any idea for products other than cisco which support ipip tunnel? I've tried Netopia, however, it doesn't support ipip tunnel. Many thanks! Cho
